WATCH-REGU LATO R.

SFECIPICATION forming part of Letters Patent No. 308,448, dated November25, 1884.

Application filed May 24, 1884.

To all whom it may cmwerlt:

Be it known that I, GEORGE I. TUTTLE, of Aurora, in the county of Kaneand State of Illinois, have invented a new and useful Improvement in\Vatch-Regulators, of which the following is a full, clear, and exactdescription.

The object of my invention is to provide a regulator that will allow ofthe finest and most accurate adjustment, and one that can be readilyused without risk of injury to the parts of the watch.

It consists in a dial, pointer, and pinion carried by the arm of theregulator, and a curved rack attached on the watch-plate, and also incertain details of construction, as hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a face view of a watch-plate with my improved regulatingmechanism. Fig. 2 is a cross-section 011 line :0 x of Fig. 1, and Fig. 3is a back face view of the regulatorarm. These figures are in enlargedsize.

A is the watch-plate. a is the regulatorarm, hung on the balance-bridgeb, as usual. On the outer end of the arm is fixed a graduated dial, a,of circular form, that carries an arbor at its center, and on the arborbeneath the dial is a pinion, d. On the arbor and above the'dial is apointer, c.

f is a curved rack of suitable length, attached at one end to plate A bya screw, 9, and h is a spring attached to the plate and bearing on thefree end of the rack, so as to retain the same in mesh with pinion d atall times,whiie allowing a certain amount of elas- The rack-plate has agraduated scale (ModelJ on its face for indicating the extent of movement of arm a, the end of which extending over the racl: is pointed. Thescale on dial 0 indicates divisions of the spaces on the dialscale to afine degree.

In order to operate the regulator the pointer c is turned by using anysimple instrument, and the pinion turning on the racl; causes arm a totravel in either direction, as the case may be. The movement of thepointer will be considerable to obtain a slight movement of theregulator-arm, so that line adjustment is possible, and the extent ofmovement is determined by the scale. It is to be observed that the dialis at a distance from the balance, so that there is no risk of injuringthe spring or wheel. If desired, the rack may be on the balance-bridge,and equally removed from the vicinity of the balance.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. In a watchregulator, the combination, with therack f, secured to the watch-plate, of the dial 0, secured on the outerend of the regulatorarm, the pinion d, and the pointer 0, the pinion andpointer being upon an arbor at the center of the dial, substantially asherein shown and described.

2. In a watch-regulator, the combination of pinion d and point-er 6,carried by the regulator-arm, and the rack f, substantially as shown anddescribed.

3. In a wa-tchregulator, the pivoted rack f and spring h, combined withthe regulator-arm and pinion thereon, substantially as described.

GEORGE I. TUTTLE.
